2. Anatomy refers to “STRUCTURE”
Anatomy of upper limb
Bones
Joints
Muscles
Nerves
Vascularization (Blood supply)

3. Bones of upper limb

4. Joints of Upper limb Sternoclavicular Acromioclavicular
Shoulder joint (Glenohumeral j )
Ball&socket
Many ligaments
Great Mobility !

5. Joints of Upper limb Elbow Joint : Synovial of hinge Articulations
Humerus with Ulna & Radius
Collateral Ligaments

6. Joints of Upper Limb Sup.Radioulnar joint Synovial of pivot
Inf. Radioulnar joint
Synovial – pivot
Allows pronation and supination of forearm

7. Joints of the Upper Limb
Radiocarpal joint
Distal radius with scaphoid and Lunate
Intercarpal joints
Carpometacarpal (2-5)
Trapezium-metacarpal (1)
Metacarpo-phalangeal
Interphalangeal

8. Muscles of Scapula If ORIGIN on scapula = Move Arm

9. Shoulder Muscles

10. Muscles of Arm: Cross elbow, Move forearm
2 Compartments
Anterior: Flexors of forearm
Posterior: Extensors of forearm
Anterior Compartment
Biceps brachii = MC nerve
Brachialis = MC nerve
Brachioradialis = Radial nerve
Posterior Compartment
Triceps brachii = Radial nerve
Anconeus = Radial nerve

11. Anterior Compartment Forearm
Medial Epicondyle
Brachioradialis
Pronator Teres
Flexor Carpi Radialis
Flexor Carpi Ulnaris
Flexor Retinaculum
Flexor Digitorum Superficialis is deep to other flexors
Anterior View

12. Posterior Compartment of Forearm
Lateral Epicondyle
Brachioradialis
Extensor digitorum
Ext Carpi Radialis Longus
Extensor carpi ulnaris
Posterior View

18. Activity List activities need flexion of fingers and thumb?
Think of tasks in which we do extension of fingers and wrist?
Name the task requires opposition of thumb????
